Laptop Keyboard Assignments

Laptops often use cords to emulate keys that are less common, in order to save some space relative to a full size keyboard. Unfortunately, each laptop is slightly different, or does not display those keys. This guide helps show what they keys are on a variety of systems I commonly use.

"Typical function" describes the default OS behavior of the key without any modifier (such as Control). Note that specific applications may assign different functions to these keys.
